Adobe Portable Document Format (PDF). With support for PDF/A and optional image over text overlays. The PDF document support requires unlocking an extra key before it can be used. For more information, refer to Unlocking Special LEAD Features

LEADTOOLS Temporary Document (LTD). This format creates a temporary file on disk that can later be converted to any of the other formats supported by the LEADTOOLS Document Writers. This format is intended to be used when creating a document with large amount of pages over multiple sessions (for example, in a server-based scenario)

Key Features:

Support for PDF/A. PDF/A is a subset of PDF obtained by leaving out PDF features not suited to long-term archiving. The resulting document is guaranteed to look exactly like the original version when viewed on the target machine. Saving with PDF/A document type may result in larger output file sizes

Extra options for the various flavors of the output documents supported. For example, adding page numbers and breaks to text files and frames (text box objects) in DOC/DOCX files

Support provided to monitor the document creation operation through a progress event. Your application can provide a visual feedback using a progress bar and a cancel button to the user to allow both monitoring and abortion of the current operation.
